1. When the pump is started, the stored water in the cabin enters the filter device through the suction plate, is filtered through the filter element 12 of the filter 1 for the first time, and then enters the second stage of filtration.

2. The water filtered for the first time has removed large particles of impurities such as silt and rust in the raw water, and the water is discharged from two outlet holes respectively. The first outlet hole (i.e. the water outlet valve 15) provides general daily water, and the second outlet hole (i.e. the water outlet valve 15) provides general daily water.
